2020-01-18iio: accel: kxcjk1013: Support orientation matrixDmitry Osipenko
Hardware could be physically mounted in any possible direction and userpspace needs to be aware of the mounting orientation in order to process sensor's data correctly. In particular this helps iio-sensor-proxy to report display's orientation properly on a phone/tablet devices.

2020-01-13iio: st_sensors: Drop redundant parameter from st_sensors_of_name_probe()Andy Shevchenko
Since we have access to the struct device_driver and thus to the ID table, there is no need to supply special parameters to st_sensors_of_name_probe(). Besides that we have a common API to get driver match data, there is no need to do matching separately for OF and ACPI. Taking into consideration above, simplify the ST sensors code.

2020-01-12iio: adis: Introduce timeouts structureNuno Sá
The adis library only allows to define a `startup_delay` which for some devices is enough. However, other devices define different timeouts with significantly different timings which could lead to devices to not wait enough time or to wait a lot more than necessary (which is not efficient). This patch introduces a new timeout struct that must be passed into `adis_init()`. There are mainly, for now, three timeouts used. This is also an introductory patch with the goal of refactoring `adis_initial_startup()`. New driver's (eg: adis16480, adis16460) are replicating code for the device initial setup. With some changes (being this the first one) we can pass this to `adis_initial_startup()`.

This header file now only includes the cros_ec_dev struct, however, is the 'include/linux/platform_data/cros_ec_proto.h' who contains the definition of all the Chrome OS EC related structs. There is no reason to have a separate include for this struct so move to the place where other structs are defined. That way, we can remove the include itself, but also simplify the common pattern #include <linux/mfd/cros_ec.h> #include <linux/platform_data/cros_ec_proto.h> for a single include #include <linux/platform_data/cros_ec_proto.h> The changes to remove the cros_ec.h include were generated with the following shell script: git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d' Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Sebastian Reichel <sre@kernel.org> Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2019-12-30iio: accel: bma180: BMA254 supportLinus Walleij
This adds support for the BMA254 variant of this accelerometer. The only difference for the simple IIO driver is that values are 12 bit and the temperature offset differs by 1 degree. Whilst wildcards in naming are normally frowned upon: The cases where I have labeled variables "25x" is where the models are identical, so as to make things easier for people that want to add support for BMA253 and BMA255.

The center temperature of the supported devices stored in the constant BMC150_ACCEL_TEMP_CENTER_VAL is not 24 degrees but 23 degrees. It seems that some datasheets were inconsistent on this value leading to the error. For most usecases will only make minor difference so not queued for stable.

2019-09-02mfd / platform: cros_ec: Reorganize platform and mfd includesEnric Balletbo i Serra
There is a bit of mess between cros-ec mfd includes and platform includes. For example, we have a linux/mfd/cros_ec.h include that exports the interface implemented in platform/chrome/cros_ec_proto.c. Or we have a linux/mfd/cros_ec_commands.h file that is non related to the multifunction device (in the sense that is not exporting any function of the mfd device). This causes crossed includes between mfd and platform/chrome subsystems and makes the code difficult to read, apart from creating 'curious' situations where a platform/chrome driver includes a linux/mfd/cros_ec.h file just to get the exported functions that are implemented in another platform/chrome driver. In order to have a better separation on what the cros-ec multifunction driver does and what the cros-ec core provides move and rework the affected includes doing: - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c driver from include/linux/mfd/cros_ec.h to a new file include/linux/platform_data/cros_ec_proto.h - Update all the drivers with the new includes, so - Drivers that only need to know about the protocol include - linux/platform_data/cros_ec_proto.h - linux/platform_data/cros_ec_commands.h - Drivers that need to know about the cros-ec mfd device also include - linux/mfd/cros_ec.h Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mark Brown <broonie@kernel.org> Acked-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Neil Armstrong <narmstrong@baylibre.com> Acked-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Reviewed-by: Gwendal Grignou <gwendal@chromium.org> Tested-by: Gwendal Grignou <gwendal@chromium.org> Series changes: 3 - Fix dereferencing pointer to incomplete type 'struct cros_ec_dev' (lkp) Signed-off-by: Lee Jones <lee.jones@linaro.org>

A few bits for the counters subsystem mixed in here as well. There are some late breaking fixes as well, which aren't so urgent they can't wait for the merge window. New Device Support * adf4371 - New driver + bindings. - Support the adf4372 PLL. Mostly ID and bindings. * ad8366 (note includes rework of driver needed to allow support for these). - Support the ADL5240 variable gain amplifier (VGA). - Support the ADA4961 digital gain amplifier (DGA). * dps310 - New driver, in several parts from different authors for this temp and pressure sensor. - Includes errata workaround for a temperature reading issue. * stk3310 - Support the stk3335, mostly ID. Features and cleanups * core - drop error handling on debugfs registration. - harden by making sure we don't overrun iio_chan_info_postfix. * docs - convert remaining docs to rst. At somepoint we'll fit these few into the main IIO docs. - improve sampling_frequency_available docs but explaining the range form. * ad_sigma_delta - Drop a pointless goto. * ad2s1210 - Drop pointless platform data null check seeing as we don't actually use platform data anymore. * ad7124 - Relax limitation on channel numbers to allow pseudo different channels. - Support control of whether the input is buffered via DT. - Use dynamic allocation for channel configuration to make it easier to support new devices. - YAML binding conversion. * ad7150 - Comment tidy up. - Consistent and simple if (ret) handling of i2c errors. - FIELD_GET and GENMASK. - Ternary rather than !!(condition) for readability. - Use macros to avoid repetition of channel definitions. * ad7606 - Add software channel config (rather that pin controlled) - Refactor to simplify addition of new part in future. * ad7746 - of_deivce_id table. * ad7780 - MAINTAINERS entry - YAML DT bindings. * ad8366 - Stop using core mlock in favour of well scoped local lock. - SPDX + copyright date update. * ad9834 - of_device_id table * adf4371 - Add support for output stage muting before lock on has occured. * adis library - MAINTAINERS entry to reflect that this now Alexandru's problem ;) * adis162xx: - Fix a slightly incorrect set of comments and print statements on minimum supported voltage. * adis16203 - of_device_id table. * adis16240 - Add of_device_id table (in two parts as first patch only used it for MODULE_DEVICE_TABLE.) * adt7316-spi - of_device_id table * adxl372 - YAML DT binding conversion. - Cleanup use of buffer callback functions (precursor to core rework). * bh1710 - Simplify getting the i2c adapter from the client. * dht11 - Mote to newer GPIO consumer interface. * kxcjk-1013.c - Add binding for sensor in display of some ultrabooks after userspace tools updated for it not be a problem to report two similar sensors. * imx7d - drop unused variables. - white space - define instead of variable for clock frequency that is fixed. - drop pointless error message. * messon_saradc - SPDX * sps30 - MAINTAINERS entry - YAML binding conversion. * st_accel - Tidy up ordering in various buffer related callbacks. This is part of a long running effort to simplify the core code. * stm32-dfsdm: - Manage the resolution cleanly in triggerd modes. - Add fast mode support which allows more flexible filter choices. - Add a comment on the reason for a 16 bit record when technically not 'required'. * st_lsm6dsx - Embed device name in the sensor_settings struct as i3c doesn't have a convenient name field to use for this. * xilinx-adc - Relax constraints on supported platforms to reflect that this can used with FPGAs on PCIe cards and hence many architectures. * counters/ftm-quaddec - Fix some formatting io MODULE_AUTHOR - MAINTAINERS entry Fixes * tools - fix incorrect handling of 32 bit channels. * sca3000 - Potential endian bug that is unlikely to bite anyone (be64 host seems unlikely for this old part). * stm32-adc - Add vdda-supply. On some boards it needs to be turned on to supply the ADC. DT bindings included. * stm32-dfsdm - Fix output resolution to work with filter orders other than 3. - Fix output datatype as it's signed and previously claimed not to be. * tag 'iio-for-5.3b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (68 commits) iio: iio-utils: Fix possible incorrect mask calculation iio: frequency: adf4371: Add support for output stage mute dt-bindings: iio: frequency: Add ADF4372 PLL documentation iio: frequency: adf4371: Add support for ADF4372 PLL dt-bindings: iio: adc: Add buffered input property Convert AD7124 bindings documentation to YAML format. iio: adc: ad7124: Shift to dynamic allocation for channel configuration iio: adc: ad7124: Add buffered input support iio: adc: ad7124: Remove input number limitation MAINTAINERS: add ADIS IMU driver library entry iio: adis162xx: fix low-power docs & reports counter/ftm-quaddec: Add missing '>' in MODULE_AUTHOR iio: core: no need to check return value of debugfs_create functions docs: iio: convert to ReST iio: adc: stm32-adc: add missing vdda-supply dt-bindings: iio: adc: stm32: add missing vdda supply iio: adc: stm32-dfsdm: add comment for 16 bits record iio: adc: stm32-dfsdm: add fast mode support iio: adc: stm32-dfsdm: manage data resolution in trigger mode iio: adc: stm32-dfsdm: fix data type ...
